Pākahi Vanadium Redox Flow, inoa piha ʻo Vanadium REDOX flow battery (VRB), he ʻano pākahiko REDOX kahi e kaapuni ai nā mea hana i ke ʻano wai. Ua puni nā pākahiko Iron-chromium REDOX mai ka makahiki 1960, akā ua hāpai ʻia nā pākahiko vanadium REDOX i ka makahiki 1985 e Marria Kacos ma ke Kulanui o New South Wales ma Australia, a ma hope o ʻelua mau makahiki o ka noiʻi a me ka hoʻomohala ʻana, ua kokoke ka ʻenehana i ka oʻo ʻana. Ma Iapana, ke ulu wikiwiki nei nā pākahiko vanadium ʻano paʻa (ʻaʻole like me EV) no nā kikowaena mana hoʻoponopono kiʻekiʻe a me ka mālama ʻana i ka ikehu makani, a ua hoʻohana ʻia a kūʻai ʻia nā ʻōnaehana mālama ikehu pākahiko vanadium mana kiʻekiʻe.
ʻO ka ikehu uila opākahiko vanadiumua mālama ʻia ma ke ʻano he ikehu kemika i loko o ka electrolyte waikawa sulfuric o nā ion vanadium o nā kūlana valence like ʻole, a me kahydraulic electrolyticHoʻokomo ʻia ke kaomi i loko o ka puʻu pākahiko e ka pamu waho. Ma lalo o ka hana o ka mana mechanical, ke kaʻapuni nei ke kaomi hydraulic electrolytic i loko o nā pahu mālama wai like ʻole a me ka loop pani o ka hapalua pākahiko. Hoʻohana ʻia ka membrane hoʻololi proton ma ke ʻano he diaphragm o ka pūʻolo pākahiko, a kahe like ka hopena electrolyte me ka ʻili electrode a hana ʻia ka hopena electrochemical. Hoʻololi ʻia ka ikehu kemika i mālama ʻia i loko o ka hopena i ikehu uila ma ka hōʻiliʻili ʻana a me ke alakaʻi ʻana i ke au ma o nā papa electrode pālua. ʻO kēia kaʻina hana hoʻohuli e hiki ai i ka pākahiko vanadium ke hoʻopiʻi ʻia, hoʻokuʻu ʻia a hoʻouka hou ʻia me ka maʻalahi. ʻO ka electrolyte maikaʻi he V(Ⅴ) a me V(Ⅳ) ionic solution, ʻo ka electrolyte maikaʻi ʻole he V(Ⅲ) a me V(Ⅱ) ionic solution, ka hoʻouka ʻana o ka pākahiko, nā mea maikaʻi no ka hopena ionic V(Ⅴ), ka hopena ionic V(Ⅱ), ka hoʻokuʻu ʻana o ka pākahiko, ka electrode maikaʻi a me ka maikaʻi ʻole no ka hopena ionic V(Ⅳ) a me V(Ⅲ) ionic solution, ka pākahiko i loko ma o ka H+ conduction. Aia nā iona V(Ⅴ) a me V(Ⅳ) ma ke ʻano o ka iona VO2+ a me ka iona VO2+ i loko o ka hopena waikawa, no laila hiki ke hōʻike ʻia nā hopena maikaʻi a me nā hopena maikaʻi ʻole o nā pila vanadium penei:
ʻElekoda maikaʻi i ka wā e hoʻouka ai: VO2++H2O→VO2++2H++e-
ʻElekoda maikaʻi ʻole i ka wā e hoʻouka ai: V3++ e-→V2+
Anode hoʻokuʻu: VO2++2H++e-→VO2++H2O
ʻElekoda hoʻokuʻu maikaʻi ʻole: V2+→V3++ e-
Hoʻohana ʻia e like me kahi ʻōnaehana mālama ikehu,nā pila vanadiumnā ʻano aʻe
1, ʻo ka mana hoʻopuka o ka pila e pili ana i ka nui o ka puʻu pila, ʻo ka mana mālama ikehu e pili ana i ka mālama electrolyte a me ka noʻonoʻo ʻana, no laila he maʻalahi loa kona hoʻolālā, i ka wā e maopopo ai ka mana hoʻopuka, e hoʻonui i ka mana mālama ikehu, inā e hoʻonui i ka nui o ka pahu mālama electrolyte a hoʻomaikaʻi paha i ka noʻonoʻo electrolyte;
2, aia ka mea hana o ka pā vanadium i loko o ka wai, hoʻokahi wale nō ka ion electrolyteʻiona vanadium, no laila ʻaʻohe loli pae o nā pila ʻē aʻe i ka wā e hoʻouka ai a hoʻokuʻu ʻia, he ola lōʻihi ka pila;
3, hoʻouka, hana hoʻokuʻu maikaʻi, hiki ke hoʻokuʻu hohonu me ka ʻole e hōʻino i ka pila;
4. Hoʻokuʻu haʻahaʻa haʻahaʻa, i ka wā e pani ʻia ai ka ʻōnaehana, ʻaʻohe hanana hoʻokuʻu ponoʻī o ka electrolyte i loko o ka pahu;
5, kūʻokoʻa ka wahi o ka pākaukau vanadium, hiki i ka ʻōnaehana ke pani piha i ka hana, ʻaʻohe haumia, mālama maʻalahi, uku hana haʻahaʻa;
6, ʻaʻohe pilikia pahū a ahi paha o ka ʻōnaehana pila, palekana kiʻekiʻe;
7, ʻo ka hapa nui o nā ʻāpana pākahiko he mau mea kalapona makepono, nā plastics ʻenekinia, waiwai nui nā kumu mea, maʻalahi e hana hou, ʻaʻole pono nā metala makamae e like me ka mea hoʻoulu electrode;
8, kiʻekiʻe ka pono o ka ikehu, a hiki i ka 75% ~ 80%, hana kumukūʻai kiʻekiʻe loa;
9. Ka wikiwiki hoʻomaka wikiwiki, inā piha ka reactor i ka electrolyte, hiki ke hoʻomaka i loko o 2min, a ʻo ke kuapo mokuʻāina hoʻouka a hoʻokuʻu wale nō e pono ai he 0.02s i ka wā e hana ana.
ʻO VET Technology Co., Ltd ka ʻoihana ikehu o VET Group, he ʻoihana ʻenehana kiʻekiʻe aupuni e loea ana i ka noiʻi a me ka hoʻomohala ʻana, hana ʻana, kūʻai aku a me ka lawelawe ʻana i nā ʻāpana kaʻa a me nā ʻāpana ikehu hou, ʻo ia hoʻi ka hana ʻana i nā moʻo motika, nā pamu vacuum, nā cell wahie &pila kahe, a me nā mea holomua hou aʻe.
I nā makahiki i hala iho nei, ua hōʻuluʻulu mākou i kahi hui o nā talena ʻoihana akamai a me nā hui R & D, a he ʻike kūpono ko mākou i ka hoʻolālā huahana a me nā noi ʻenekinia. Ua hoʻokō mau mākou i nā holomua hou i ka automation o nā lako hana hana huahana a me ka hoʻolālā laina hana semi-automated, e hiki ai i kā mākou hui ke mālama i ka hoʻokūkū ikaika ma ka ʻoihana like.
Me nā hiki R & D mai nā mea koʻikoʻi a hiki i nā huahana noi hope loa, ua hoʻokō nā ʻenehana koʻikoʻi a me nā ʻenehana koʻikoʻi o nā kuleana waiwai kūʻokoʻa i nā hana hou ʻepekema a me ka ʻenehana. Ma muli o ka maikaʻi o ka huahana paʻa, ka hoʻolālā hoʻolālā maikaʻi loa a me ka lawelawe ma hope o ke kūʻai aku kiʻekiʻe, ua lanakila mākou i ka ʻike a me ka hilinaʻi mai kā mākou mea kūʻai aku.
Nā nīnau i nīnau pinepine ʻia
No ke aha e hiki ai iā ʻoe ke koho i ke kauka holoholona?
1) loaʻa iā mākou ka hōʻoia waiwai lawa.
2) ʻO ka hoʻopili ʻoihana e hōʻoiaʻiʻo ana i ka pono o ka huahana. E hoʻouna palekana ʻia ka huahana iā ʻoe.
3) ʻoi aku ka nui o nā kahawai logistics e hiki ai ke hāʻawi ʻia nā huahana iā ʻoe.
Q: Ke kālepa nei ʻoe i kahi ʻoihana a mea hana paha?
A: He hale hana mākou ma mua o 10 mau makahiki me ka palapala hōʻoia iso9001
Q: Pehea ka lōʻihi o kou manawa hoʻouna?
A: ʻO ka maʻamau he 3-5 mau lā inā loaʻa nā waiwai i loko o ka waihona, a i ʻole 10-15 mau lā inā ʻaʻole i loko o ka waihona nā waiwai, e like me kāu nui.
Q: Pehea e hiki ai iā Iget ke hāpana e nānā i kou maikaʻi?
A: Ma hope o ka hōʻoia ʻana o ke kumukūʻai, hiki iā ʻoe ke koi i nā laʻana e nānā i ka maikaʻi o kā mākou huahana. Inā makemake ʻoe i kahi laʻana hakahaka e nānā i ka hoʻolālā a me ka maikaʻi, e hāʻawi mākou iā ʻoe i ka laʻana no ka manuahi inā ʻoe e uku i ka ukana wikiwiki.
Q: He aha kāu mau ʻōlelo o ka uku?
A: Ke ʻae nei mākou i ka uku e ka Western union, Pavpal, Alibaba, T/TL/Cetc..no ke kauoha nui, hana mākou i ka 30% koena waiho ma mua o ka hoʻouna ʻana.
inā he nīnau ʻē aʻe kāu, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou e like me lalo nei
